Housing and Building Standards Quebec 4 Minutes Read · published February 11, 2026 Flag of Quebec

Montréal, Quebec property owners and neighbours may encounter overgrown grass and noxious weeds that violate municipal maintenance rules. This guide explains how to identify a likely bylaw breach, the steps to report it to the City of Montréal, what enforcement action to expect, and practical tips to prepare a complaint. It is written for residents, property managers, and community groups who need a clear, step-by-step approach to reporting and following up on vegetation and lot maintenance issues.

How to report an overgrown lot or weeds

Follow these action steps to make a clear, effective complaint to the city so enforcement can proceed.

  • Document the problem with date-stamped photos and the property address.
  • Check the borough (arrondissement) responsible for the property to find the correct complaint portal or phone number.
  • Submit a complaint online or by phone to the City of Montréal’s bylaw enforcement service; include photos, address, and a short description.
  • Keep records of your submission date and any reference or file number provided by the city.
  • If you are the property owner, confirm whether you have any active permits or exemptions before filing.
Provide clear photos and exact address to speed up inspection scheduling.

Penalties & Enforcement

The City of Montréal enforces property-maintenance and vegetation requirements through its municipal enforcement services. Official city pages and boroughs describe processes for inspection and orders but do not always list fixed fine amounts or escalation tables on a single public page; specific monetary penalties are not specified on the primary public pages for general complaints and must be confirmed with the enforcing department or the municipal court.

  • Enforcer: municipal bylaw enforcement (Service d'application des règlements or the borough enforcement office).
  • Fines: not specified on the main public complaint pages; the city may issue fines, daily continuing fines, or order corrective work.
  • Escalation: initial inspection, notice to comply, followed by orders and penalties for continuing non-compliance; exact timelines and repeating-offence amounts are not specified on the public complaint summary pages.
  • Non-monetary sanctions: the city can issue orders requiring the property owner to cut grass or remove weeds; if the owner fails to comply, the city may carry out the work and recover costs from the owner.
  • Appeals and review: contestation usually proceeds through municipal procedures or the municipal court; specific time limits for appeals are not specified on the general complaint pages and should be confirmed when you receive a notice or ticket.
  • Defences/discretion: municipal officers have discretion and there may be exceptions or permits; if you believe you have a reasonable excuse or a permit, inform the inspector and provide documentation.
If you receive a notice, act quickly and keep all documentation to preserve appeal rights.

Applications & Forms

The city commonly accepts complaints through online borough portals or a central reporting page; no universal paper form is required for most reports. If a specific permit or exemption is needed, borough pages or the bylaw text will list the form name and submission method; consult the borough or the city complaint confirmation for any required forms.

What inspectors check

  • Height of grass and presence of invasive or noxious weeds that affect public safety or neighbours.
  • Accumulation of brush or vegetation that creates a nuisance or hazard.
  • Evidence of repeated non-compliance after prior notices.
Inspectors typically document conditions with photos and a written report before issuing an order.

Action steps after enforcement starts

  • Note the compliance deadline on any notice and arrange corrective action or a request for review before that date.
  • If work is done by the city, keep the invoice and appeal within the municipal process if you dispute costs.
  • If ticketed, follow the ticket instructions to contest in municipal court and observe time limits printed on the ticket.
